Canadian superstar Justin Bieber has admitted that one of his ambitions with his new album 'Believe' was to create something that would give his career some longevity.

Speaking about the general perception of teen heartthrobs, Bieber explained that he wants to be an exception to the stereotype and hopes his new tour will change the minds of anyone who has ever doubted his ability and dedication:

"I don't want to be just another teen heartthrob. I know some people are waiting for me to fail, thinking, 'Oh, his time's up.' Well, I like being the underdog, and this tour is my chance to take things to the next level."

Referring to his forthcoming 'Believe' world tour, Bieber added:

"I've never put in more hours preparing, because I want [the tour] to be perfect. I want it to be an event. I'm with a personal trainer every day. I'm rehearsing every day. I want people to see this tour and go, 'Wow, that was something I didn't expect.'"

He also told USA Today that the late King of Pop, Michael Jackson, is a constant source of inspiration to him: "I've been watching videos of his concert tours over and over, he's my inspiration. When my team gets together, we're always asking, 'What would Michael do?'"
